Satoru had never taken care of anyone before, but when he saw Masato struggling with balancing school and raising his baby brother Eiji, he couldn't stand by and let it happen. It was Satoru who proposed the idea for his group of friends and him to help Masato out so he wouldn't drop out. It was the right thing to do, especially since Masato was involved. Especially since his own life seemed to be anything BUT right. Satoru knew his father, Hideaki, to be a perfectionist, but this was never so true when it was apparent that he would never measure up to Hideaki's standards. When it became clear to Satoru that he would never meet these standards, he stopped caring. He began to rebel and act out, causing problems and getting arrested. His friends were all too happy to join in on the antics. But deep down, Satoru wanted Hideaki to care. He wanted Hideaki to feel something. But as the years passed the gulf between his father and him only widened. There seemed to be no chance of recovery. Satoru's only solace was with his friends. With caring for Eiji. And...Masato. A young man who had unknowingly captured his heart. But can their friendship become more when there is so much going on in both of their lives? And what happens when Masato finds himself tangled in the drama? The Heart of the Boy is the second book in the I Am Big Brother series, following the evolving relationship between Masato and Satoru, and the trials they face along the way.
